Please excuse me for my "poor" descriptions before. The kinf of "Link" tool: ENVI, and ERDAS as well, provide a "Link" tool with which one can open, side-by-side, images of the same region and while panning, zooming or resizing one of the images, these actions are automatically mirrored to the othe image.
Why is this useful: I provide a (small) screenshot to illustrate my need (!). In this example I try to visually interpret the land cover on the image which is on the right (it is a SPOT4 acquisition). To support this task, whenever it is difficult to recognize something, I use the orthophotos (in my screenshot located on the left side). The tool is capable to link multiple images with the same or different resolution, with the pre-condition that they are georeferenced (In this example the object of interest is a small football(soccer!) stadium... !) . Again... I am just putting questions... I think, in most cases, asking doesn't hurt. Is there an alternative way to replace this method (supporting a visual interpretation with ancillary data)? Would it be very difficult to implement something like that? Thank you, Nikos. Michael Barton wrote: > > I still don't understand what you mean by this (I don't use Imagine or > ENVI).
